摘要在评估缺血性心脏病的无创性方法中，SPECT心肌灌注显像（MPI）是大家公认的显像方法，但MPI受到一些因素的影响，如组织不均一性导致的衰减、扫描时间长、辐射等。近年来出现的心脏专用碲化镉锌（CZT）相机越来越受到人们的广泛关注，该设备有先进的CZT探测器、采集方法及重建算法。心脏专用CZT相机的计数率、空间分辨率和能量分辨率较传统SPECT显著提高。该文就心脏专用CZT相机的相关临床应用进展进行综述。

abstractsAmong non-invasive methods for the assessment of ischaemic heart disease, myocardial perfusion imaging (MPI) using SPECT tracers is firmly established and well-known by physician and pa-tients. However, MPI is still affected by several drawbacks such as attenuation due to non-uniform tissue, motion artefacts due to time-consuming scan and radiation exposure. The dedicated solid-state cardiac camera using cadmium zinc telluride(CZT) solid-state detectors emerged in recent years. The camera has gotten more and more attention. The camera has advanced CZT detector, acquisition and reconstruction method. The count rate, spatial resolution and energy resolution of the CZT SPECT have been enhanced significantly. This paper would review the clinical application progress of CZT SPECT.
